ROPE-CONTROLLER.

SPECIFICATION forming part of Letters Patent No. 637,820, elated November 28, 1899.

Application filed .Tanuary 13 1898. Serial No. 666.549. (No model.)

T0 all whom, it may concern:

Be it known that I, GsoAR E. OsBoENE, a citizen of the United States, residing at Ashtabula, in the county of Ashtabula and State of Ohio, have invented certain new and useful Improvements in Rope-Controllers; and I do hereby declare the following to bea full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in means for regulating or controlling various pulley-blocks; and it consists of certain details of construction and arrangement of parts deemed necessary for accomplishing such result, the object of my invention being to provide a reliably-eicient controlling device or regulator to be used in connection. with any variety of block and tackle, by means of which little attention will be necessary on the part of the operator, as my improved governor is thoroughly selfacting.

It will be hereinafter made clear that my governing device is practically a pulleyblock within itself, though it is to be used in connection with the pulley-block of ordinary construction.

In the accompanying drawings, Figure lis a side elevation showing my invention as applied to use in connection with block and tackle of the usual construction. Fig. 2 is a transverse section of Fig. l on line ct a. Fig. 3 is a longitudinal central section of the body portion or housing of my improved governor. Fig. 4 is a top plan view of the governor illustrated in Fig. 1, while Fig. 5 is a perspective detail of the portion of the clutchplate, Fig. 6 being a central longitudinal section of my clamping device, showing the same in position for engaging the rope.

It Will be understood that my improved governor' will be useful for any and all of the purposes for which block and tackle are employed, as upon derricks, slaughter-house winding-drums, elevators, dec.

It will be clear that while I have shown in Fig. l my invention as applied to use upon improved governor may be made of any preferred material and that it consists of but a few simple parts readily constructed and assembled in their respective operative positions, and while I will hereinafter describe the preferred construction and accessories deemed necessary in the embodiment of my governor, yet I desire this application to comprehend any substantial equivalent thereof and that I be not strictly confined to the eX- act showing I have made.

In materializing my invention I provide the base or body section l, upon which is integrally formed or otherwise attached the rib or plate 2, upon which the other parts forming my governor are pivotally mounted, as will be hereinafter fully specified.

Upon the rib-section 2 I pivot, preferably at one end thereof near its upper edge, the housing 3, which is oblong in general outline and consists of the two parallel side sections 4 and 5, joined together or integrally formed at their upper edge by the connecting-section 6, and between the forward ends of said sections I mount upon a suitable shaft, as by bolt or rivet 7, the grooved pulley 8, while the extreme pointed ends of said sections are connected with each other or integrally united by means of the reinforcing end section 9, while the opposite ends of said sections terminate in the pedal or controlling-stem l0, by means of which the entire housing 3 may be moved upon its pivot 1l. Upon the plate or rib 2 I also pivot at the outer end thereof the bifurcated controlling-lever l2, the ends l2a of which'are designed to lie upon both sides of the stem l0 and loosely receive the same. The ends l2L are sufficiently separated to permit the stem l0 to be received between them, thus providing at the point where said ends unite with the lever l2 the shoulder or head 12b, which is designed to engage the upper side of the end of the stem lO and enable the same to be forced downward by the outward movement of said lever, thereby setting upa binding condition upon the rope. In addition to the pivot I3, by means of which said lever is mounted upon the plate 2, I also provide the rivet or bolt 14, which passes through the bifuroated end of the lever from side to side thereof immediately under the stem 10a sufficient distance below the same to permit the too Vss

free play of said stem between vthebifurcat'ed ends of Vthe lever ywhen the latterisv moved from side to side, the purpose of such movement being hereinafter fully described and fully set forth.

In order to provide'thatthe rope., (indicated at-15,) which is designed topass between the curved ceiling of the housing 3 and theupper face of the rib or plate 2, may be more relii ably grasped by said parts as the lever 12 is'. moved outward and the stem 10 thereby forced downward, I .providethat-the upper face of,-` said plate or rib may be roughened orcorrugated, as 'indicated at 16,V While, if desired, it will be understood that the ceiling of the ho'usi -izng 3 may also be roughened, if deemed necg -essary f In Fig. 5 I have shown a section of the p-re-' -ferred 'form-.of vcorrugations 16, whichrnay be integrally"formed in the edge of the plate 2@ onconsist of a metal plate to be irmly attached g in position incase said plateor rib 2-is formed of. wood. The stem end is preferably .so formed vthat a shoulder or odset 17 will be, provided upon yeach side ofthe body lat ithsi point, which will cheek Aan undue inward? :movement of the lever 12, while -t-oo greatan outward .movement will be checked bytheI leverlcontacting with the outer end of `the 'stem lO. The shoulder 17 is simplyanfoiset yformed V:by abruptly reducing the width 'off the body in order to .form the stem 10. p 1

For the purpose of illustrating one of .the uses .of my invention I have shown a pair .of` simple :double-.pulley blocks properly con-1 `neoted with each-other, though it will zbeclear .that any form .of block having any'preterred` .ployed .and that Ythe coperation of .myrau-.tol 'maticgovernor will beequally asefcient and reliable where a block ot' simple or the mosti complex construction is used or whenever-.a :rope is to be lheld and wit-hout thecopera-` .tion` of Iblock and tackle of any kind.- :In using my invention the automaticgov-.- ernor is secured directly to .the floor, ceiling, f. wall, or .other .preferred point by bolting or' Aotherwise attaching the base 1 in position l and the free ,end of the ropepassed'under the pulley 8, .and .thence through the body 3 `tietween: the sides 4 and 5 above the plateor rib i .2, .and it will be clear that the clamping oper- Vation of thegovernor will be automatic, inasmtuch :as ithe pull upon the rope Willelevate the tapered end 9, thereby causingzthe curved inner :face of the section G to bind ltightly against .the rope and force it against the corruig-ated face 16 of the rib 2, thereby preventing the .further longitudinal movement thereof,.and 'thus checking further movement 'of the .pulley-wheels in the pulley-blocks, (indicated at 18 and 19,) the former block .being provided with the hook .2O for attachment to the ceiling or'other point, while the latter isV provided with thehookfl, designed to engage -directly with the load to be raised. K .When .itis desirable to ease or loosen the of said stem'and the consequent release of the rope 15. It will alsobe clear that when forany reason it is desirabler to moretightly bind said rope in position an outward movementofthe lever 12 will bring-about such result', as thestem 10 will be `forced downward by the shoulder or head 12?, it being understood that in case the device is attached toa ceiling or other high point said lever will be madeof sufficient length to lenable it to be .easily-grasped bythe operatortrom his .posi- -tion upon the door. It will .be furtherappar-v :entthat for all .ordinary practical purposes -said ile-ver' mayv be entifrelyomitted, .if desired, in whichcaselthe foot may be brought to :bear y -or iregulatingzi-ts moveln ent by a reduction .of

such pressure. l v v My invention will be ifoundfto lbe especially desirable as :a reliablel means tor directing the action-of the .pulley-blocks upon :elevators and ederricks con trolling :heavy loads, Ibut will 'also he ydesirailile lforevery ,varietyof wor-kof this character, .whether 11i g-ht or` heavy.

Having thus .fully described my invention, what I claim as :nemanddesire .to 'sec-ure by Letters Patent, is-

1.- As an improvement in rope-controllers, .a s upponting-.base shavinga rib, a 'housingcarfrying a pulleyandfitting-over and piyotedfto said rib, a rope passing between said rib and housing anda `lever pivoted :to said rib.:and

engaging an extension Vformed .oln .said hous- 1 for .ropes comprisingthe base having a rib thereon., a housing having a longitudinal groove designed to receive said riband carry- :ing a .pulley upon .one end, .a rope running in said groove .between .said fhousingand riiband over said pulley, and-a lever-.pivotedltoisaid `rib and ^engaging said housing whereby the rope will `loe vreleased at will, Aall `arranged as rset forth.

In yla .clamping -devi'ce `for ropes, a ibase `havinga rib provided with-serrations,:a .housing provided with separated `side. Sections adapted to receive .said rib between them and .carryinga pulley ,near its forward end, means bythe ropeinterposed .between said `parts will -be automatically -secured or manually re- ICO IIO

4. In a controlling` device Afor ropes, a ibase having a rib, a housing pivoted to said rib and having a pulley in one end and an extension upon its oppositeend, a rope extending between said housing and rib, a bifurcated lever having the ends 12a the shoulder or head 12b and boltlLl attached to said base by said ends and designed to receive the extended end of the housing between the same whereby when said lever :is moved outward said shoulder will bear upon said stem and force the same downward thereby clamping the rope while an opposite movement of the lever will release said rope, as specified and for the purpose set forth.

5. In a rope-clamping device a suitable support or base, a housing pivoted to said base,V

a pulley mounted in one end of said housing and a pivoted bifurcated lever having a crossbar designed to cooperate with an extension formed on said housing whereby the latter may be moved at the will of the operator to release the rope passing between said housing and base, all arranged as set forth.

6. In a clamping device for ropes, a base having a rib provided with serrations, a housing carrying a pulley at one end and having an extension upon its opposite end, said housing being pivoted to said rib, a rope passing over said pulley and between said housing and rib and a lever pivoted to said rib and cooperating with said extension whereby the rope passing between the housing and rib may be released at will to be again automatically clamped by the action of the weight when said device is released, all arranged as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
